This useful study presents computational analyses of over 5,000 predicted extant and ancestral nitrogenase structures. While the data and some analyses are solid, the study remains incomplete in ...

The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different ... makes up hair and nails Enzymes Catalyse biological ...

Each enzyme is made from proteins made of these twisting and folding amino acids, and therefore the enzyme has a unique shape. This structure is held together by weak forces between the amino acid ...

Proteins can be big or small, mostly hydrophilic or mostly hydrophobic, exist alone or as part of a multi-unit structure ... and bone in vertebrates. Enzymes are another type of protein, and ...
